They do, when pulling at WOT. The problem is that unlike at the pulling track where the tractor starts with pulling a light load that gets progressively heavier, at home, most situations require maximum pull to start the load moving, and then it gets progressively easier. That is where a hydro will beat on a manual transmission. No clutch to slip to keep torque up and horsepower (and therefore speed) down.

Why on earth would you think hydro has to be run wide open?! My MF 1855 with Johnson loader, was almost never over 1500-1800 RPM when moving dirt, stone air pushing 3"-4" trees over.

Entry level hydros in LT's tend to make high pressure, and therefore heat, when pushed as in climbing slopes. The Tuff Torq K46 can only deliver 2.73 hp and 131 or 171 ft-lb of torque to the rear axle, depending on the final drive ratio.

It's a bit different with the heavier hydros.The Sundstrand in your 1855 is capable of delivering 11 hp to the rear wheels at 1500 psi. The axle torque in low range is almost 800 ft -lb at that pressure and it takes a lot of ballast to keep the tires hooked to the ground.

Basically, you have a bit more than twice the tractor weight but 4 times the hydro, and you haven't even begun to tap the hydros' reserve at 1500 psi. You will break the Peerless well before you hit max torque capability.

All my horti tractors are old fashioned gear boxes would not swap them they are Gutbrod 1032 s

The mower I use to cut the grass on the caravan park is a 4 wheel drive Stiga mower and is hydraulic drive to go forward you press forward with your toe to go backwards you press down with your heel it takes 20 hours to cut the grass if it was a gear box it would mean a lot of gear changes

That makes sense, I know I never Revved that one much and it did a lot of work.
